Hastelloy B-3 alloys are designed to withstand high stress and high temperatures. One of the main advantages of Hastelloy B-3 is its exceptional resistance to hydrochloric acid, regardless of temperature or concentration. Additionally, this alloy is highly resistant to other corrosive substances.

The main difference is their composition; Hastelloy B3 has slightly lower oxidation resistance than the more corrosion-resistant Hastelloy B2. Both can be formed into round bars for heat exchangers, pressure vessels, chemical reactor pumps, and valve components, among other uses.

1. Hastelloy B3 flanges provide exceptional resistance to many corrosive chemicals, such as hydrochloric acid, sulfuric acid, phosphoric acid, and organic acids. They also exhibit resistance to pitting, crevice corrosion, and stress-corrosion cracking. 2. Hastelloy B3 maintains its mechanical properties and erosion resistance even at high temperatures, making it suitable for applications that require elevated temperatures. 3. Hastelloy B3 flanges are versatile and find applications in different industries, including chemical processing, petrochemical, pharmaceutical, and waste treatment. 4. Hastelloy B3 can be easily fabricated into flanges using standard manufacturing processes like forging, machining, and welding.
